Even after all the patches I have already submitted for this
-ftrack-macro-expansion business, some test cases where errors happens
on tokens that are defined in macros see their output change in an
incompatible way, when you run them with or without
-ftrack-macro-expansion.

I think this is expected, because the (spelling) locus inside the
definition of the macro pointed to with -ftrack-macro-expansion is
different from the locus of the expansion point of the macro pointed
to without -ftrack-macro-expansion.

In those cases this patch either adjusts the test case and forces it
be run either with -ftrack-macro-expansion, or it just forces it to be
run without -ftrack-macro-expansion.

There are so many libstdc++ tests that were failing because of that
benign issue that I preferred to just run them with
-ftrack-macro-expansion diabled, after inspecting each of them to be
sure there was nothing more serious underneath.  I believe we can latter
turn on -ftrack-macro-expansion there on a case by case basis.

Boostrapped on x86_64-unknown-linux-gnu against trunk with and without
-ftrack-macro-expansion turned on.

Hey hey! Looking good Dodji. Can't wait to use this stuff.

Seems perfectly reasonable. I volunteer to look at the
libstdc++testsuite  changes once your patches are in checked in to
trunk.
